Assessing the establishment, growth, and survival of West Gulf Coast southern pines in east TexasThis article is part of a larger document. View the larger document here.
West Gulf Coast provenance loblolly (Pinus taeda L.), longleaf (P. palustris Mill.), shortleaf (P. echinata Mill.), and slash pines (P. elliottii Engelm.) were planted in east Texas to compare initial growth and survival across various soil types. Containerized seedlings were planted in December 2015 on three sites in Shelby, Houston, and Cherokee counties using a randomized complete block design. Seedlings were measured initially January- February 2016 and again January-February of 2017, 2018, and 2019. Three years after planting, survival was greatest (76.4 percent) on the study site with fine sandy loam textured soils that were well drained to somewhat poorly drained and was lowest (26.4 percent) at the study site with high Texas leafcutter ant (Atta texana) activity. Tree heights and diameters were greater for loblolly and slash pine than shortleaf and longleaf pine.
